Make a Musical Mobile

It's a wonderful little contraption that will allow you to make a musical mobile! See that hook? You just hang your mobile from that hook, wind up the crank, and your mobile will turn as the music plays. National ArtCraft, the supplier that sells these cases, also sells interchangeable music box movements (the piece that actually makes the music) to go inside. There are many songs to chose from, and the best part is that the website allows you to play a tiny mp3 to hear a sample. The individual parts are cheap, but they do have a $30 minimum order requirement.
